      With the Tesla  Roadster and  other  plugin ( 插入式) electric vehicles hitting the road,

demand is growing for accessible refueling points to recharge them．Carbon Day Automotive,

a Chicagobased company,has now demonstrated a solarpowered recharging point,known as

the Solar PlugIn Station,which lets motorists easily charge their cars using electricity that has

been produced without any environmental damage．

      The Solar PlugIn Station has gone on show in Chicago as part of the city's bid to host the

2016 Olympic Games．According to Carbon Day Automotive,the Solar PlugIn Station on

show in Chicago is part of the vital infrastructure(基础设施) required for electric vehicles in

Chicago and was the focus of a recent visit by the International Olympic Committee．

      These solarpowered electricity points will be used daily to fuel the city's electric vehicles

with power from the sun．By producing the electricity from pollutionfree solar cell,the CO2

emissions are reduced to zero．

      "Solar energy and electric vehicles are a partnership that is one more step to reducing our

dependence on foreign oil," says Richard Lowenthal,CEO of Coulomb Technologies．Coulomb

Technologies recently developed the components (部件) required for individual recharging stations,

marketed as ChargePoint Networked Charging Stations．Carbon Day Automotive is the Midwest

distributor for the ChargePoint stations．

     The Solar PlugIn Station consists of giant solar panels (电池板) that shade the tiny ChargePoint

Networked Charging Station．The solar panel is connected to an underground battery pack,ready

for everyday refueling．

     "Without these stations it would be like driving around in a traditional car without the availability

of gas stations," says Scott Emalfarb,CEO at Carbon Day．"The day of true plugin electric vehicles

will be here sooner than most people realize and the world needs to be ready to accommodate them．"
